He said in a BBC interview, which was taken in France at G7 summit that all depended on their EU friends and partners.
When he was pressed on chances, he stated that he thought it was going to be a touch and go. However, important thing was to be ready to come out with no deal.
Donald Tusk said to the PM that EU was open to other options to Irish backstop.
Katya Adler, BBC Europe editor, said that on Sunday, Mr Johnson and the European Council president held positive talks.
She added that Mr Tusk insisted the position of EU that whatever alternatives were to be proposed they had to be “realistic” and instantly operational.
An official of EU added that the meeting had basically “restated known positions” and that it was Brussels’ hope for the situation to be unblocked by new elements.
The two men had a clash over who should be blamed when there is no-deal Brexit.
Mr Johnson had previously said that the UK should leave on October 31st, “deal or no deal”, but there were very less chances of a no-deal Brexit.
BBC asked the prime minister if medicine would still be accessible to people in case of a no-deal Brexit to which he guaranteed its accessibility yet he prepared the customers for unforeseen difficulties.
At G7 summit, he emphasized on discard of the backstop from the present withdrawal agreement, stating the UK could be locked in rules of EU, if trade is not made after Brexit.
He said that he thought that in past few days, Brussels and other capitals of Europe had realized how serious the problem was for U.K.
Mr Johnson stated he was optimistic that it would be understood by the EU that there’s a chance to make a deal.
He also added that if there was no deal then U.K would keep a considerable part of the £39bn that Theresa May had made an agreement to pay the EU, in the withdrawal agreement she landed.
The G7 summit – a union of leaders of the largest economies of the world- is coming in just over 2 months of the schedule, at October’s end, of U.K to leave the EU.
The apparently known as “divorce deal” that that Mrs May struck with the EU was thrice rejected by the British MPs.
